If you tell me what you are trying to accomplish, I can tell you where to look. The whole field of TE is rife with invention and reinvention. Every TE module manufacturer will give you advice and also tell you their modules are the best. I've been involved in the design and manufacturing of TE cooled consumer products since 1987. My company manufacturers all the TE cooling "engines" for Igloo Products (we have literally built several million units). I'd be happy to steer you to some GuRu's who will help you. This is gratis. I'm not looking for business.
